Description
A drop-in replacement for aging electrical systems, the P140 restores functionality to vintage setups with 40 amps of single-pole protection. It utilizes a reliable thermal-magnetic trip mechanism to safeguard against overloads and short circuits. This unit mounts into classic Pushmatic load centers, seamlessly replacing discontinued Bulldog, Gould, and ITE P140 breakers. Operating at 120VAC with a 10 kAIC interrupting capacity, it features the signature push-button actuation for resetting.Specifications

Product FAQs
5 answersCan the Siemens P140 replace older Bulldog or ITE breakers?
Yes. Siemens manufactures the modern Pushmatic line, making the P140 a direct replacement for discontinued Bulldog, ITE, and Gould P140 circuit breakers.
Will this breaker fit in standard Siemens load centers?
No. The P140 features a specialized bolt-on design that is strictly compatible with Pushmatic load centers. It will not fit standard Siemens plug-on or bolt-on panels.
How is the P140 breaker operated and reset?
Pushmatic breakers utilize a push-button actuation rather than a standard toggle switch. To reset a tripped breaker, push the button fully to the OFF position, then push it again to engage the ON position.
What type of wire can be used with the P140 terminals?
The screw and clamp terminals are rated for both copper and aluminum conductors, accepting wire sizes from 8 AWG to 4 AWG.
How can you visually verify the status of this Pushmatic breaker?
The push-button mechanism includes a mechanical indicator flag that displays whether the breaker is in the ON or OFF position, allowing for quick visual verification of the circuit status.
